You are tasked with writing a program which will write a monthly account summary of customers' transactions at the bank at which you are employed. The monthly transactions are stored in a file called transactions.txt in the follow form 123 d45.10 d50.45 d198.56w45.67 The first entry is the account number, the remainder of the line, variable in length, contains all the transactions of the particular customer for the month: If the entry begins with a d, the number that follows is the amount of deposit; If it begins with a w, the number that follows is the amount of withdraw The customer "database" is stored in another file, accounts.txt which has entries of the form 123 daffy 34.67 where each line contains the customer's account number then their name, followed by the current account balance of the month. Your program will write report in the following form ( given the above data) Account Number Name Beginning Balance Ending Balance Amount Deposited Number of Deposits Amount Withdrawn Number of Withdraws 123 daffy S34.67 S283.11 $294.11 $45.67 The report is to be written to a file called account report_MONTH.txt, where MONTH is a user entered month name

Explanation / Answer

working c++ code compiled on ideone.

#include <iostream>
#include <fstream>
#include <iomanip>
#include <cstdlib>
#include <string>
using namespace std;

struct PersonAcct // struct account holds customer info
{
int acct_num; // customer account number
string name; // customers name
int acct_bal; // customers account balance
};

void Accounts_update(PersonAcct &accountStructure, ifstream &account);
void Transactions_update(PersonAcct &accountStructure, ifstream &transaction , double &withdrawls, double &deposits, int &num_of_deposits, int &num_of_withdrawls);
void Print_Report(PersonAcct &accountStructure, ofstream &monthlyReport, int num_of_withdrawls, int num_of_deposits, double withdrawls, double deposits);
string get_month();
int get_account_num();

int main()
{
ifstream account;   //the accounts.txt file stream
ifstream transaction;   //the transactions.txt file stream
ofstream monthlyReport;   //the output report
string month;   //the month
PersonAcct accountStructure;//structure, the current account
int prog = 'y';
double w, d;   //the value of each
int withdrawls, deposits;   //number of each

while(prog == 'y')
{
accountStructure.acct_num = get_account_num();  
month = get_month();   //input to be taken

account.open("accounts.txt");   //files to open
transaction.open("transactions.txt");
monthlyReport.open("account_report_" + month + ".txt");

if( !account || !transaction ) // test for unsuccessful file opening
{
cerr << "Cannot open file: " << "accounts.txt or transactions.txt" << endl << endl;
exit (0);
}

Accounts_update(accountStructure, account); // from account.txt
Transactions_update(accountStructure, transaction, w, d, withdrawls, deposits);
cout << "NO PROBLEM BEFORE OUTREPORT";
Print_Report(accountStructure, monthlyReport, withdrawls, deposits, w, d);

account.close();   //files to open
transaction.close();
monthlyReport.close();

cout << "Would you like to run the program again? y or n ";
cin >> prog;
cout << endl << endl;
}

return 0;
}

string get_month()
{
string month;
cout << "What month are we making a report file for? ";
cin >> month;
cout << endl << endl;
return month;
}

int get_account_num()
{
int accountNum;
cout << "What is the account number? ";
cin >> accountNum;
cout << endl << endl;

return accountNum;
}

void Accounts_update(PersonAcct &accountStructure, ifstream &account)
{
int placeHolder1;
while(!account.eof())
{
account >> placeHolder1;
if(placeHolder1 == accountStructure.acct_num)
{
account >> accountStructure.name;
account >> accountStructure.acct_bal;
}
cout << "HI!";
}

}

void Transactions_update(PersonAcct &accountStructure, ifstream &transaction, double &withdrawls, double &deposits, int &num_of_deposits, int &num_of_withdrawls)
{
int placeHolder2;
char ch = 'k'; //to set a default value
double value = 0;   //for adding/subtracting values

deposits = 0.0;   //initializations
withdrawls = 0.0;
num_of_deposits = 0;
num_of_withdrawls = 0;

while(!transaction.eof())
{
transaction >> placeHolder2;

if(placeHolder2 == accountStructure.acct_num)
{
while(ch != ' ')
{
transaction.get(ch);
if(ch == 'd')
{
transaction >> value;
deposits += value;
num_of_deposits++;
value = 0;
}
if(ch == 'w')
{
transaction >> value;
withdrawls += value;
num_of_withdrawls++;
value = 0;
}
}
}
}
}

void Print_Report(PersonAcct &accountStructure, ofstream &monthlyReport, int num_of_withdrawls, int num_of_deposits, double withdrawls, double deposits)
{

double endBalance = accountStructure.acct_bal - withdrawls + deposits;

monthlyReport << "HI!";
monthlyReport.width(26);
monthlyReport << "Account Number : " << right << accountStructure.acct_num << endl;
monthlyReport.width(26);
monthlyReport << "Name : " << right << accountStructure.name << endl;
monthlyReport.width(26);
monthlyReport << "Beginning Balance : " << right << accountStructure.acct_bal << endl;
monthlyReport.width(26);
monthlyReport << "Ending Balance : " << right << endBalance << endl;
monthlyReport.width(26);
monthlyReport << "Amount Deposited : " << right << deposits << endl;
monthlyReport.width(26);
monthlyReport << "Number of Deposits : " << right << num_of_deposits << endl;
monthlyReport.width(26);
monthlyReport << "Amount Withdrawn : " << right << withdrawls << endl;
monthlyReport.width(26);
monthlyReport << "Number of Withdraws : " << right << num_of_withdrawls << endl;

}

I have used the struct as mentioned by you in the program. The required functions are added to help and do the transactions as required in the code.
